(1A) At a movie theatre, the child ticket price is x dollars and the adult ticket price is $3.50 more
than a child’s ticket. One evening, 41 child
tickets were sold and 65 adult tickets were sold.
Which of these expressions represents the total
ticket sales, in dollars?
A) 41 65 350 x   . 
B) 41x  65x  3.50
C) 41 65 350 x x    . 
D) 41 65 350 x x    . 

I am pretty sure it is B obv that is the only one that makes enough sense (x+3.50)x65 (x)41 and the only one that makes sense to me is B!

Step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
